IMPROVEMENT IN BOTTLE-STOPPERS.

Specification forming part of Letters Patent No. 149,331, dated April 7,1874; application tiled January 12, 1874.

To all whom it may concern:

Beit known that I, GHAELEs W. Oscfoon, of Haverhill, in the county ofEssex and State of Massachusetts, have invented a new and usefulImprovement in Bottle-Stoppers; and do hereby declare the same to befully described in the following specification and represented in theaccompanying drawing, in which- Figure 1 is aside elevation of a bottleprovided with my invention, the same representing the bott-le as sealedFig. 2 is a longitudinal section of the same; and Fig. 3, a sideelevation, showing the stopper as turned back or away from the mouth ofthe bottle.

The object of my invention .is to provide a simple and effective deviceto be applied to the mouth of a bott-le, preserve-jar, or other articleof like character, in order to perfectly seal such vessel, so as toprevent the ingress of air, or the escape of gas or other iuid or androvi n its lower surface with J(prennmoemmdmmbber;orvotls'uitable eastic or ,i saineV `leimi-l" v\s`ecid'thereto by gluing, or in any othersuitable manner. Through the axis of the stopper or cap is a smallcountersunk hole,'c, to receive the lower end d of a screwrod orthumb-screw, C, which is formed as shown in Eig. S-that is to say, thelower portion of such is formed plain, or without threads, and of a lessdiameter than the threaded portion, such diameter corresponding withthat of the hole in the cap or stopper. Such end, after being insertedin the said hole, is upset, so as to coniine the screw and capinseparably together, while, at the same time, it allows the screw-rodto be freely rotated therein. D is a metallic yoke or cross-piece,through the center of which the thumb-screw C passes, 011e end of suchyoke being hinged to the collar a by means of a link, d, the oppositeend of the yoke having a notch or catch, e, to receive the eye of alooped link, f, whose lower end is hinged or connected with the collara, as shown in Figs. l and 2.

Having described the construction of my invention, its operation is asfollows:

In order to seal the bottle, the stopper is to be placed over the mouththereof, and the eye of the locking-link is next to be passed into thenotch or catch ofthe yoke; then, by simply turning the thumb-screw inthe proper direction, the cap or stopper may be brought into contactwith the mouth or neck of the bottle with any required degree of forceto produce a perfectly air and gas tight connection.

In unsealing the bottle, in order to remove the contents thereof, orenable the bottle to be filled, the thumb-screw is to be turned backwardsufficiently to enable the eye of the fastening-link to be removed fromits catch in the yoke, when the cap or stopper may be turned into theposition as shown in Figs.

From the above, it will be seen that by my peculiar construction andarrangement of the parts of the said device, the whole may be readilyapplied to a bottle or jar, and the stopper closed upon or removed fromthe mouth .thereof with great ease, while the combined arrangement ofthe screw, the cap, and the yoke prevents such parts from becomingseparated, mislaid, or lost.

Having described the construction and operation of my invention, what Iclaim is The combination of the cap B, the thumbscrew C, and yoke D,constructed and connected in manner as described, with the collar a andhinged links If/the whole being applied together and to the neck of abottle, or

its equivalent, as and for the purpose set forth.
